I once installed a private DNS with advertising block lists on a home network level. My SO was not amused, as her Android based games with "watch an advertisement for ingame credits" now did not work anymore.

Nowadays only the TV sets and my own devices are set to use this (pihole) DNS server. So that I can at least watch Disney+ without ads.

Yes, I already run Pi-hole on a Raspberry Pi at home, but I had to disable it due to complaints.
